UNITED STATES EDWARD-W. HILL,, OF CHICAGO, ILLINOIS.

LOOSE-LEAF LEDGER.

Application filed Apri1 19, 1321. Serial No. .16 2,586.

To all whom it om ypcoacern:

Be it known that I, EDWARD W. HILL, a citizen of the United States of America, residing at Chicago, 'Illinois,have invented a new and useful Loose-Leaf Ledger, of which the following is a specification.

My invention relates particularly to binders ot a character set forth in my Patent 111,224,455 dated May 1st, 1917.

One object of my inventioiris to provide an improved and simple tor nof construction toiacilitate the assemblage of the parts 01' the binder.

Another object is to increase the security of the parts when assembled.

Another object is to keep the parts in their proper relative position when the binder is opened out for the transfer of sheets from one side to the other.

Anotherobject is to facilitate the use;of the construction in what is known as ma chine posting.

Fig. 1 is a perspective viewof a binder embodying the 1 111'11310181116111313 of any invention. 1

Fig. 2 is aperspective view on a smaller out and arranged for what is commonly termed machine posting.

Fig. 3 is a perspective view showing parts of the binder partially assembled.

Fig. 4: is a perspective View of a connecting clip. a

Fig. 5 shows two of the leaf-supporting posts and extensions.

Fig. 6 is a perspective view of two at the post extensions.

A support 10 carries posts such as 11 and 12 and a COII'GSPOHCllDg support 13 carries coniplenientary posts 1 1 and 15 adapted to telescope respectively with posts such as 11 and 12 when the parts are assembled in the position of Fig. 1. As shown, the free end of one meinber o'f each pair-of telescoping posts, as 11 and 15, presents a socket to receive a suitably rounded end of the other member of the pair, as 12 andl l. While it is desirable to alternate the socket and round ended .posts on a single support in any other arrangement may be employed so long as each socket ended post telescopes with a post having a rounded end when the binder covers are closed. Covers such as 16 and 11" are preferably hinged to the sup ports 10 and 13 respectively. The rear sup- I and llOld 16111 in POSltlOIl. the 1113111181 illustrated 111 ObVlOllSl.

port 10 has secured to it a back member 18 which cooperates with the inner back member 19 carried by the support 18 to position the leaves and hold the parts in their proper relative positions. I describe as the face of each hackmember 18, 19 that sur'facewhich is turned towards the covers 16, 17 when the binder is in normal or closed position as shown in Fig. 1. members opposite to the faces I call the backs, i. e. those surfaces which are seen iirFig. 8. In the form shown, the faceot back 18 .is provided with one or more headed studs or projections 20 whose shanks slidably engage in the slots 21 of the inner back 19 whenthe parts are assembled with the face of back .18 turned towards the back of back 19 in the position of Figs. 1 and 3. This stud and slotengagement gives substantial security in addition toithe telescopic connection of the posts.

At each end of theinner back 19 lpretergably providea flange and these flanges are so located and constructed with relation to the endsof the outer back 18that theyserve as positioningguides in assembling the parts, with the back members ttace tojback as shown in Figs. 3. These flanges also serve asiguides in assembling the parts with the back members back to back as shownin Fig. 2.

A plurality of spring-pressedlocking pins 2 3 are carried by the outer back 18 and are adapted to engage in the holes or re cesses 24 inthe inner back. These pins are adapted :to be simultaneously operated by means 01? a plunger 25 and mechanism such as shown in. my former Patent tl;'].,22- 1-,.. The back 18 serves as a housing for this inechanisn'i.

lVhen theparts of the binder are assembledback to back as shown in Fig. 2 for the transfer of sheets from one set of posts to the other, they are held in predetermined relativeposition by means ot' a clip 26, in the form of a separate member the two sides of which are preferably resilient so asto embrace the back members 18 and 19 The clip may be provided with a knob orprojection 27 to engage inasuitablerecess in one of the back members to hold the clip yieldingly in place.

To facilitate the transfer of sheets from the rear post sections 11 and 12 to the front post sections 14 and 15, I preferably pro- The surfaces of theback 1 vide pointed extensions 28 and 29 which are adapted to engage the posts 14: and 15. The extensions 28 are tubular at their lower ends to slip over the posts 14 and the rear ends of the extensions 29 are reduced in diameter so as to lit into the ends of the posts 15. The construction of the parts is such that when they are assembled, as shown in Fig. 5, the posts and their extensions are uniform in diameter so that the leaves can be slipped on or off without danger of catching.

The construction is such that the binder and leaves may be used as an ordinary loose leaf ledger for the entry of items by hand and for the insertion and removal of leaves when desired, as set forth in my former patent. In addition, the construction is such that by using the temporary extensions 28 and 29, the transfer of leaves is very greatly facilitated so that the ledger may be used efficiently for machine posting as well as hand posting. After the posting is completed and the parts are in the position shown in Fig. 2, the post extensions and the clip 26 are removed and the parts are assembled as indicated in Fig. 3.

I claim:

1. In a loose leaf binder, a support having posts extending therefrom and a back memher, a second support and posts extending therefrom and adapted to telescopically engage the other posts, a back member extending from said second support, headed studs carried by one of said back members, the other back member having slots to receive the shanks of said headed studs and having open ends to permit the supports to be disconnected and placed with their back members back to back for the transfer of loose leaves from the posts of one support to the posts of the other support.

2. In a loose leaf binder, two supports, posts carried by said supports and telescopi-ally engaging each other, back members carried by said supports and extending parallel. with said posts, and flanges extending outwardly from the inner back member and adapted'to serve as positioning guides in engagement with the ends of the outer back member when the posts are telescopically connected and also when the posts are disconnected and the back members of the binder are placed back to back.

3. In a loose leaf binder, separable supports having leaf-engaging telescopic posts and cooperating back members, and a clip removable from all the other parts for engaging said back members to hold said parts in n'edetermined relative position independently of said posts and a detent on said clip to hold the same in effective position.

4. In a loose-leaf binder, front and rear covers including separable back IDGHIlJGlS, telescopic posts carried thereby, means for holding the parts together with said posts in telescopic engagement, and a channelshaped clip having resilient flanges adapted to frictionally engage the face portions of the back members to hold them in predetermined relative position when assembled back to back.

5. In a loose leaf binder, front and rear covers, telescoping posts carried thereby, means for holding the parts together with the posts in telescopic engagement, detachable extension members adapted to engage some of said posts when the posts are disconnected, and detachable means independent of said posts and independent of said extensions for holding the parts of the binder in predetermined relative position to prevent the posts from being brought into alignment when said extensions are in place.

6. In a loose leaf binder, front and rear members having cooperating leaf-supporting members, back members placed face to back along one edge of the binder and having slot and stud connections and variably operable interlocking pins and holes for holding the parts together.

7. In a loose-leaf binder, front and rear members having cooperating leaf-sup mrting members, back members carried by said front and rear members and having slot and stud connections and interlocking members for holding said front and rear members together, and a detachable clip having resilient flanges for holding said front and rear members in predetermined relative position when said back members are assembled back to back.

8. In a looseleaf binder, front and rear members having cooperating leaf-support ing members, separable back members carried by said front and rear members and having slot and stud connections and interlocking members for holding said parts together, other means independent thereof for holding the parts of the binder in predetermined relative position when said leaf-supporting members are separated and the back members assembled back to back, and extension members cooperating with some of said leaf-supporting members and independent of the interlocking members, serving to facilitate the transfer of sheets from the other leaf-supporting members.
